Description

Method and system for indicating the status of a push button switch and the functions controlled thereby
Technical Field
The application relates to the technical field of automobile electronics, in particular to a method and a system for indicating the state of a button switch and a function controlled by the button switch.
Background
With the development of automotive electronics and the increasing demands for driving safety, more and more vehicles are beginning to support emergency call functions (e.g., ECALL functions). After an accident or an anchor of the vehicle, the driver and the passenger of the vehicle can trigger the emergency call function by pressing a button switch (e.g., ECALL button) for triggering the emergency call function, thereby giving a distress signal and reporting the position of the vehicle. Alternatively, the emergency call function of the vehicle may be triggered in other ways, for example by signals from crash sensors or temperature sensors provided on the vehicle, so that the vehicle can automatically signal a distress signal and report the location of the accident vehicle even when the driver and the passenger are unconscious and cannot ask for help.
In a real environment, since a button switch (e.g., ECALL button) for triggering an emergency call function is hardly used, it cannot be judged whether the button switch for triggering an emergency call function can normally operate. In addition, after the push button switch is pressed, it cannot be intuitively judged whether the emergency call function of the vehicle has been successfully triggered. It is therefore desirable to provide an intuitive way of indicating whether a push button switch for triggering an emergency call function is able to function properly and whether the emergency call function was successfully triggered.
